Modeled and observed transverse position-velocity (PV) diagrams in HH46-47. Left panels: transverse position-velocity diagrams perpendicular to the outflow axis, inferred from the jet-driven shells simulation in Fig. 5 and Sect. 5.2, at t = 10000 yr inside 400au-wide cuts at projected heights of (a) 6.6 × 10¹⁶ cm and (c) 8.9 × 10¹⁶ cm, with an outflow inclined by an angle i = 55° from the line of sight. Here only the core-originated material mass contribution is shown. Right panels: ¹²CO(2–1) emission of HH46/47 along two 450au-wide cuts at projected heights of (b) 8.1 × 10¹⁶ cm and (d) 1.0 × 10¹⁷ cm from the central source, with red ellipses showing best-fit models by wide-angle wind-driven shells.
